uncoated optical Windows/substrates

Description

Various dimensions substrates made from BK7, uVFs, IrFs, caF2, Znse, sapphire, MgF2.

standard substrates are laser grade polished on both surfaces. these substrates are ideal for beamsplitters, windows, partial reflecting mirrors etc.

Laser components require highly polished substrates as well as high performance coatings. scattering, damage of laser light can occur if the substrate is made of inferior material or if it is inadequately polished. For uV, very high power applications and ultrashort pulses we recommend using uVFs substrates. BK7 substrates are economical solution for laser components used in many applications in laboratory as well as in devices and instruments.

Altechna provides various dielectric and metallic coatings on optical substrates.

Features

• Ideal for beamsplitters, windows, partial reflecting mirrors etc

• uVFs substrates are recommended for the uV and very high energy applications

• Windows up to 500 mm diameter are available

Precision uncoated optical Windows/substrates

Description

Being designed as precision windows/substrates to distinguish by supreme surface polishing quality as well as surface flatness and parallelism, which makes the windows indispensable article for most precision demanding applications. special polishing technique is used to drive surface smoothness and flatness nearly to perfection. this product is ideal substrate to produce mirrors/polarizers for high power applications since laser induced damage threshold (LIdt) value is closely related to surface polishing quality. Negligible parallelism error (<5 arcsec) causes minimum misalignment errors, when component is repeatedly inserted and removed, this particular property makes it first choice item when one needs substrates for beamsplitters and thin film polarizers with minimal beam deviation.

Features

• superior polishing quality (10-5 s-d)

• Negligible parallelism error (<5 arcsec)

• Ideal for low scatter demanding applications

• same polishing quality applies to both surfaces

• Minimum misalignment errors when window is repetitively inserted and removed

PcV/PcX substrates

Description

If you have a task to build up a beam expander or reducer, at least a couple of lenses will be needed. If an optical line has to withstand high energy density, reflecting elements are prefered over refractive optics. reflecting focusing and defocusing optics are also perfect when dealing with ultrashort pulses. concave and convex substrates, which are listed below, can be coated with gold, silver or aluminum. Laser line or broadband dielectric coatings on these substrates are also available. If necessary, latter coatings can feature optimized gdd values.

Powell Lenses

Description

the Powell lens has an advantage over cylindrical lenses because later one produces a poorly illuminated line, limited by the non-uniform gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the light in the central area while increasing the light intensity at the line’s end. the outcome is uniformly illuminated line used in all manner of machine vision applications.

Features

• generates uniform laser line

• Fan angle from 1° up to 90°

• Line uniformity better than 25% total variation in line intensity

• Line straighness better than 0.1%

• custom made lenses also available

achromatic Lenses

Description

cemented achromatic duplet lenses are optimized to provide excellent chromatic and spherical aberrations free performance. optimized composition of two lenses, where one is made of dense flint and second of crown glass, assures much tighter focus than singlet spherical lenses due to minimized longitudinal and transverse spherical aberrations. they also feature nearly constant focal length across wide range of wavelengths. standard achromatic duplet lenses cover two ranges – visible (400 nm – 700 nm) and near infrared (700 nm – 1050 nm). single line, dual line and different than standard broadband configurations are also available. If you do not have design or drawing of required achromatic lens, Altechna engineers will help you to make one. Please contact Altechna by phone or email for drawings and Zemax files.

Features

• VIs and NIr broadband standard designs

• available in two standard diameters: 12,7 mm and 25,4 mm

• Nearly aberration free performance

• customized lenses available

Plano-convex axicons (conical lenses)

axicons (conical Lens)

Description

Plano-convex axicons are conical lenses which are used for variety of applications. When followed by a conventional spherical lens, axicons can focus laser light to a ring shape with annular focus. this feature can be used in hole drilling, microscopy and medical applications. another interesting feature of axicons is a possibility to transform gaussian beam into non-diffractive Bessel beam in the near field. Bessel beams can be used in atom or molecule guiding applications.

Altechna offers two types of plano-convex axicons: regular and precision. regular axicons will create annularly shaped beam whereas precision axicons will also transform gaussian beam into a Bessel beam. You can choose accordingly, depending to your specific application.

Plano-concave axicons (conical lenses)

Description

Plano-concave axicons have a plano surface in combination with a concave conical surface. concave axicon produces a ring shaped image along the axis from a point light source (e.g. gaussian laser beam). due to specifics in fabrication process, a hole in the center of concave surface is needed. diameter of the hole is typically 1 mm. different coatings can be applied on the polished surfaces of axicons. When coated with Hr coating, concave conical surface can be used as a conical mirror in some specific applications.

dispersing Prisms

Prisms

Description

dispersing prisms have three 60° angles therefore they are also referred to as equilateral prisms. It provides advantage over diffraction gratings where higher orders diffraction effect is unwanted. typical applications is wavelength angular separation, where the prism is placed in a beam path to refract the beam twice. common scheme is to use the prism in minimal deviation angle, which is achieved by aligning the wavelength of interest to travel in parallel to the prism base. this ensures, that angles of incident and refracted beams are equal in respect to corresponding surfaces. this alignment provides benefit of maximum clear aperture and least overall reflection loss for p-polarization.

right-angle Prisms

Description

right angle prisms are used to direct beams at 90° by using the hypotenuse face for total internal reflection (tIr). these prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads, because they are easier to mount, and deform much less than mirrors in response to external mechanical stress. as long as acceptance angle limitations for tIr from the roof faces are not exceeded, the right angle prism can also serve as a retroreflector, reflecting a beam back.

dielectric coatings

dielectric coated optics

Description

dielectric coatings consist of layers with different refractive indices. there are three major techniques used for dielectric coating: electron-beam deposition (e-beam), ion-assisted electron-beam (Iad) and ion beam sputtering (IBs). all of these processes are quite similar in their principle. they consist of evaporating some coating material and deposit it on the substrate. the difference lies in the deposition energy.

Because of low energies involved when using electron-beam deposition, thin film contains bubbles and micropores like a sponge. these will eventually fill with water, which will change the refractive index of the coating and thus the properties of the optics. (this is known as “environmental shifting”). the presence of water also lowers the damage threshold of the optics: when exposed to an intense light, the water will tend to vaporise and dislodge off bits of the coating. Finally, even in the absence of water, inhomogeneities of coating layers decrease the theoretical damage threshold. the positive points about this technology is that it is cost effective, widespread and very versatile. the coating itself is also slightly flexible, which makes the optics more resistant to mechanical stress.

Ion-assisted electron-beam is an intermediate technique, between ion-beam sputtering and e-beam. so are its results.

Ion beam sputtering involves energies 100 times higher than e-beams. as a result the molecules of the coating layers form covalent bound when deposited. the resulting coating is free from bubbles or pores, more homogeneous, more durable, has higher damage threshold and is more repeatable and controllable. It also exhibits lower scattering and absorption properties, and overall higher specifications (more broadband, steeper transitions when needed, better spectral stability…). this is high precision coating, and the surface roughness can be controlled at better than 1 Å rMs (!), that is <λ/5000. of course, this comes at a higher cost (atom-by-atom removal is very slow), and even worse, it is limited in the types of coatings it can handle: most of the uV coatings for instance involve fluorides which dissociate when sputtered. In this case, e-beam is the only option.

each coating is special and over the years in the photonics field we have learned that flexibility is the key to meet high demands of our customers. therefore our coatings are done using different technologies which are chosen for separate coatings individually. Here is our list of coating technologies available at Altechna

• electron beam evaporation

• Ion assisted deposition

• Ion beam sputtering

each technology is different and is used according to requirements of spectral sensitivity, damage threshold, hardness, surface quality etc.

Description

Hr laser line mirrors (Hr) provide optimized performance at certain wavelength and certain angle of incidence (aoI). Mirror consists of substrate and multilayer coating stacks which help to achieve high reflectance at specific laser line wavelength at any designed angle of incidence. Laser line Hr coatings are used for external beam manipulation applications where even slight losses may be intolerable. coatings are provided by electron beam evaporation with/without ion assistance coating technique.

e-beam Hr coatings are the most common dielectric coatings in laser optics market as this technology was leading for few decades, and only in recent years it started facing competition with other technologies.

Hr right angle retroreflector

Description

ultrashort pulse back-reflection task requires group delay management. due to this reason common retroreflector prism is not applicable as it introduces considerable group delay dispersion which distorts pulse’s temporal shape. Hollow configuration of right angle retroreflector, consists of two Hr coated mirrors, featuring total reflectance higher than 99.6%. Moreover, group delay dispersion (gdd) of Hr coatings is optimized to be <20 fs², what makes Hr right angle retroreflector a perfect solution for fs applications.

Features

• Hollow configuration

• reflectance >99.6% per surface

• Mirrors are deposited on uVFs substrates

• Negligible pulse dispersion

Low Loss Hr Mirrors

Description

Low loss mirrors are also referred to as IBs mirror due to ion-beam coating technology. the mirrors provide maximum reflectance at certain wavelength range and certain angle of incidence (aoI).

IBs technology stands out by multiple advantages against other coating techniques. due to fully automated control of deposition process coatings distinguish by high repeatability, sharper features, tighter tolerances. IBs thin films feature higher density, durability, high-damage-threshold, impenetrable to water vapor, which make them resistant to environmental conditions such as heat, humidity and pressure.

IBs coatings distinguish by nearly all specification being supreme to the ones provided by other coating technologies. It allows to minimize scatter in the dielectric layers which is limiting factor, then reflectance higher than 99.9% is targeted.

our selection of ion-beam sputtered coatings covers wavelength range of 343 - 1550 nm.

Features

• Provide maximum reflectance at certain wavelength range and certain angle of incidence (aoI)

• coatings are provided by ion beam sputtering (IBs) technique

• resistant to environmental conditions

• Various dimensions are available on request


• High repeatability

• reflectance higher than 99.9%

Non-Polarizing Plate Beamsplitter

Non-polarizing beamsplitting plates exhibit a polarization insensitive performance.

Description

In comparison to non-polarizing beamsplitter cubes, our plate beamsplitters feature outstanding performance. cubes typically cause energy loss at approximately 10%, because of absorption in hybrid metal/dielectric coatings where typically laser induced damage threshold varies in a range of approximately 0.3 J/cm2. Non-polarizing beamsplitting plates design comprises only dielectric layers, thus damage threshold is much higher and exceeds 6 J/cm2. separation of polarizations rs–rp typically is lower than 5%. Because of this feature beamsplitters are suitable for use with unpolarized light or light of any other state of polarization. standard items have working band width of several tens of nanometers, which makes it versatile. For example beamsplitters designed at 1025 nm - 1095 nm can be used with Yb:KgW, Yb:Yag, Nd:Yag, Yb:glass, Nd:glass lasers. For usage with femtosecond lasers, Altechna has designed beamsplitters at 800 nm and 400 nm, which do not influence pulse width, as coatings are gdd compensated. Non-standard wavelengths and sizes are available upon request.

Description

Low gdd ultrafast mirrors are designed for femtosecond applications to provide an optimized performance at certain wavelength and angle of incidence (aoI). this is achieved by careful selection of coating stacks to combine high reflectivity and low gdd value (from -10 fs2 to 10 fs2 at design bandwidth) at the same time. such coatings are used for external beam manipulation applications where pulse broadening effect is undesirable. Low gdd ultrafast mirrors are intended for ti:sapphire, Nd:glass, er:glass or Ytterbium doped host based lasers working in femtosecond regime. Variety of catalogue components allows to choose the right mirror for fundamental wavelength as well as for it’s harmonics.

Laser output coupler

Description

output coupler (oc) is a partially reflecting dielectric mirror used in a laser cavity. It has a function to transmit a part of intracavity optical power in order to get lasing. output couplers listed below can be found in stable resonators, as they have a spatially constant reflection/transmission (r/t) value, which is the main property of such kind of mirror. such cavity’s parameters as pump power threshold, maximum output power and laser efficiency highly depends on r/t ratio of output coupler. thus choosing a right output mirror for a cavity design is quite crucial moment. For user’s convenience Altechna maintains commonly used output couplers for high intensity intracavity use. rear surface is antireflective coated in order to minimize Fresnel reflections. concave mirrors help to maintain teM00 spatial mode within the resonator while wedged mirror deflect Fresnel reflection that could be amplified within resonator and form secondary (parasitic) pulse.

Features

• suitable for use in high intensity intracavities

• rare surface ar coated

• curved mirrors with various values of roc are available

Variable reflectivity Mirrors

Features

• Improves beam shape and quality

• Variable/locally defined reflection

• Highest available central reflectance value rr (max) – 35%

• custom design available (substrate shape, wedge, radius, wavelength)

Description

In order to have better beam quality, i.e. in non-stable resonators, variable reflectivity mirrors can be used. High intensity of the laser beam requires use of components with a high damage threshold. dielectric coatings are best suited to meet these requirements. Altechna offers variable reflectivity mirrors with dielectric coatings, designed for wavelengths in the range from 266 to 2500 nm.

Description

Wavelength separator has been known by many names invoked by different applications: dichroic mirror, beam combiner, harmonic beamsplitter, etc. this product is used to separate (or combine) spectral regions in space by exploiting dielectric thin film design. typical applications for wavelength separator are filtering fundamental wavelength remains from second harmonic, or letting the pump wavelength pass into the resonator through the back mirror. catalog items are designed for most common laser wavelengths, but Altechna also offers custom design wavelength separators in terms of wavelength, size and performance.

dual Laser Line Mirrors (dHr)

Description

dual laser line reflecting mirrors (dHr) provide optimized reflectance at two certain wavelengths at certain angle of incidence (aoI). these multilayer coating stacks help to achieve the highest possible reflectance at two specific laser line wavelengths at any designed angle of incidence. Laser line high reflective coatings are used in external beam manipulation applications where losses are intolerable.

Features

• designed to reduce reflectance of an optical component to near-zero for a specific wavelength

• Laser line anti-reflection coatings in range 0.19 - 10.6 µm are available

Miscellaneous

• coatings are provided by ion beam sputtering (IBs) or electron beam evaporation with/without ion assistance coating techniques

Broad Band ar coated Windows (BBar)

Description

Broad band ar coatings are designed to reduce reflectivity of optical component to near-zero for broad wavelength range.

Broad band ar coatings working in the range of 190 nm to 10.6 µm are available.

these multilayer broadband anti-reflective coatings increase transmission of optical element for a broad spectrum. therefore, it is ideal for a wide range of multi-wavelength laser and white light sources. the wavelength range and reflectivity of the coating depends on the angle of incidence.

Metallic coated optics

Description

Metallic coatings can be used at any angle of incidence because they have extremely broadband reflectance.

We offer gold (au), silver (ag) and aluminum (al) high reflectance coatings formed by vacuum deposition. all metallic reflectors can be over-coated with dielectric film of MgF2 or sio2 in order to prevent oxidation of the metallic surface and provide abrasion resistance.

elliptical Flat Mirrors

Description

When the maximum possible clear aperture is required, the best choice is elliptical flat mirrors. due to unique geometry of substrate, the aperture becomes circular when mirror is rotated by 45° around the minor axis. List of standard mirrors contains 16 different items. 4 different sizes, scaling from 12.7 mm up to 50.8 mm, and 4 types of metallic coatings are available. the most common aluminum coating features a fair reflection in uV, visible and mid - Ir wavelength ranges. Protected silver coatings assures the highest reflectance of all metal coated mirrors in the visible wavelength range. Protected gold is the most efficient coating over the entire Ir range. However, if higher reflectance is needed, the best choice is dielectric coated elliptical mirrors; Altechna can also offer such custom solutions.

Features

• Broadband protected metallic coatings

• dielectric Hr coatings are available

• circular clear aperture

off–axis Parabolic Metal Mirrors

Features

• aluminum substrate mirrors

• available in 30°, 60°, or 90° off-axis

• Mounting plates also available

Description

the main property of off-axis parabolic mirror is to focus light at an angle with beam propagation axis. this allows to avoid comatic aberration (or coma) that would emerge in case of using spherical mirror at an angle. off-axis parabolic mirrors come into assistance where usage of transmitting optics is limited, for example due to chromatic aberrations, group velocity dispersion (gVd) or spectral bandwidth. standard items comprise parabolic mirrors machined by diamond turning technique and coated with protected gold and silver coatings.

cylindrical concave Metallic coated Mirrors

Description

cylindrical concave metallic coated mirrors are used for focusing light to a thin line without chromatic aberration. Being metallic coated, mirrors work as reflectors in broadband spectral range. Most common application for cylindrical mirrors is either beam expansion or line generation. Altechna offers gold, silver and aluminum as standard coatings, but other type mirrors coatings such as chrome, copper, dielectric high reflection or partial reflection are available on request.

right angle Prism Mirror

Description

When precise and rigid mounting of bending mirror is needed, right angle prism mirrors provide more advantage than plate mirrors. Mirrors are designed to reflect light that is externally incident to hypotenuse of the prism. Prism angular tolerance of 90° angle is in range of several arc minutes (or arc seconds for precision type). easy mounting does not require further alignment to bend a light at exact 90° angle, what makes the mirrors ideal for rigid optical systems. Four standard metallic coatings are provided. the most common is aluminum coating, which features a fair reflection in uV, visible and mid - Ir wavelength ranges. other type of aluminum coating is labeled as “uV enhanced”, which means it is designed for uV applications. Protected silver coating is best suited for application in visible wavelength range, while protected gold is the most efficient coating over the entire Ir range. However, for maximum reflectance and highest LIdt, the best choice is dielectric coated mirrors. Altechna provides wide range of standard design dielectric coatings, but custom coatings are also available.

Waveplates (Phase retardation Plates) Brief overview

Waveplates (Phase retardation Plates)

Altechna offers wide range of zero order (Zo), low order (Lo) half (λ/2) or quarter (λ/4) waveplates for uV, VIs, NIr and Ir (for any wavelength in 240-9000 nm range).

Waveplates are made from materials which exhibit birefringence. the velocity of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. this difference in velocities gives a rise to phase difference. at any specific wavelength the phase difference is governed by thickness of the waveplate.

Half (λ/2) waveplate. a linearly polarized beam incident on a half wave crystal quartz waveplate emerges as a linearly polarized beam but rotated such that its angle to the optical axis is twice that of the incident beam. therefore, half-waveplates can be used as continuously adjustable polarization rotators. Half-waveplates are used in eletrooptic modulation, as a variable ratio beamsplitter when used in combination with a thin film polarizer or polarizing cube, or in general to rotate the plane of polarization.

Quarter (λ/4) waveplate - thin-film compensator. If the angle between the electric field vector of the incident linearly polarized beam and the retarder principal plane of the quarter-waveplate is 45 degrees, the emergent beam is circularly polarized. When a quarter waveplate is double passed, i.e. by mirror reflection, it acts as a half waveplate and rotates the plane of polarization to a certain angle. Quarter waveplates are used in creating circular polarization from linear or linear polarization from circular, ellipsometry, optical pumping, suppressing unwanted reflection and optical isolation.

Features

• Waveplates for any wavelength in the 240-9000 nm range

• air-spaced Zo waveplates for high energy applications

• Waveplates for many wavelengths are available from stock

• custom design waveplate assemblies are available on request

Miscellaneous

• Zero order (Zo) waveplates are generally preferred since they are least sensitive to variations in wavelength, angle of incidence and temperature. to suit different applications, air spaced or optically contacted (see drawings on next page) Zero order compensated phase retardation plates are available from Altechna

• the air-spaced construction enables to use the waveplate for high power laser applications. the damage threshold is more than 10 J/cm2 for crystalline Quartz Waveplates, more than 20 J/cm2 for High Power Waveplate and more than 5 J/cm2 for achromatic Waveplates.

Description

Altechna is offering a wide range of zero order (Zo) and low order (Lo) waveplates for uV, VIs, NIr range (for any wavelength in 240-2600 nm range). all waveplates we provide are made from excellent quality laser grade crystalline quartz material.

Zo waveplate is constructed by two quartz plates with their fast axes crossed. the difference in thickness between the two plates determines the retardance. Zo waveplates offer a substantially lower dependence on temperature, angle and wavelength change than conventional monolithic Lo waveplates.

to suit different applications, air-spaced or optically contacted Zo compensated phase retardation waveplates are available from Altechna.

the air-spaced construction enables to use the waveplate for high power laser applications. the damage threshold is more than 10 J/cm2 for 10 ns pulses @ 1064 nm.

Material crystalline quartz and MgF2





<λ/4 @ 632.8 nm



coatings BBar on each surface





Description

an achromatic waveplate (aWP) is a pair of crystal quartz and magnesium fluoride plates.

Because of the difference in dispersion in these uniaxial positive crystals it is possible to calculate thickness of each plate so that birefringent phase shift in assembly changes very slowly over a certain wavelength range. this is a way to obtain achromatic zero order waveplates. such aWPs are necessary for various devices and may replace a number of ordinary quartz waveplates operating at a single wavelength only. We can offer series of achromatic Waveplates with phase shifts shown in graphs below.

Description

a fine array of parallel conducting wires with period smaller than that of wavelength of incident radiation will transmit one polarization and reflect the other. the component of the radiation whose electric vector is perpendicular to the direction of the wires and induces current in the wires will be transmitted and the parallel vector reflected. Altechna’s Mid-Ir polarizers are produced by holographic method (i.e. laser interferometry) or mechanically ruled. these polarizers do not induce beam displacement, are not affected by diverging or converging beam, have wide acceptance angle without degradation of performance.

custom spatially Variable WaveplatesDescription

spatially variable waveplates (sVW) fabrication is based on inscription of self-organized nanogratings inside fused silica glass using a femtosecond laser. rapid prototyping enables adaptation of every element to the specific needs of end user (slow axis and retardance distribution, structure clear aperture, substrate shape and thickness) without high additional development costs.

sVWs are spatially variable retardance plates which enables tailored control of spatial polarization also for high power lasers. sVWs embedded in bulk of fused silica glass have high damage threshold which is at least 10 times higher than that of liquid crystal devices.

Fig. 2. spatially variable waveplate examples (from left to right) apodizing aperture, Fresnel lens and sinusoidal phase grating (shown in cross polarized light).

Fig. 3. “International year of light 2015” logo and interference color calibration pattern fabricated in bulk of fused silica glass.

orientation of induced nanogratings orientation is always perpendicular to laser beam polarization that is used for writing, therefore it is possible to fabricate predefined slow axis distribution patterns (Figure 2). one of the most common spatially variable waveplate is s-waveplate. s-waveplate is a super-structured waveplate which converts linear polarization to radial or azimuthal polarization. other patterns, such as Fresnel lens, “soft” aperture, dammann gratings, flat-top and airy beam converters, sinusoidal phase and fork-shaped gratings can be easily realized using this technology.

sVWs have a very broad range of applications from material processing to spinoptics in plasmonics.

Features

• Wavelength range from 400 nm to 2000 nm

• Half-wave or quarter-wave converters available

• size from 1 mm to 15 mm

• transmission from 30% to 90% (* wavelength dependent)

• custom slow axis and retardance patterns

Polarization rotators

Description

Polarization rotator is a good alternative to retardation waveplate when it comes to rotation of polarization at certain angle. Polarization rotation is caused by property, called optical activity, which is natural to quartz crystal and other substances that are enantiomorphous. this property is caused by crystal lattice structure, that lacks mirror symmetry due to helicoidal chains of sio4 units oriented along c-axis in quartz structure. depending on chain rotation direction there is “right” and “left” quartz which rotates polarization clockwise or counter-clockwise respectively. Polarization rotators are c-cut so rotation of polarization occurs independently of component’s rotation around optical axis, thus component is alignment-insensitive and the only requirement is that incident beam must be perpendicular to rotator’s aperture. Altechna offers rotators with fixed 45° or 90° rotation of polarization with antireflection coatings for design wavelength. For convenient use all rotators are mounted in black anodized aluminum mount. device is good replacement for waveplate, for usage along with narrow band lasers.

Description

thin film polarizers are used for high energy applications.

they have high damage threshold reaching 10 J/cm² @ 1064 nm for 8 ns. thin film polarizers are used as an alternative to glan-taylor laser polarizing prisms or cube polarizing beamsplitters.

typically, BK7 or uVFs dielectric coated thin film polarizers separate the s and p polarization components of high energy laser beams and are intended for intra and extra cavity usage.

typical extinction ratio tp/ts is 200:1 and it is achieved at 56° aoI (Brewster angle). For optimal transmission thin film polarizer should be mounted in an appropriate holder for angular adjustment.

Polarizing cubes for Medium energy applications

Description

Polarizing cubes are suitable for specified wavelength (250-2200 nm) on four input and output ar coated working surfaces. Polarizing beamsplitter cubes split randomly polarized beams into two orthogonal, linearly polarized components: s-polarized light is reflected at 90° angle while p-polarized light is transmitted.

each beamsplitter consists of a pair of high precision right angle prisms cemented together with a dielectric coating on the hypotenuse of one of the prisms. typical damage threshold of these cubes is >0.3 J/cm2 @ 1064 nm for 10 ns pulses at 20 Hz.


Material BK7, uVFs, sF glasses


clear aperture >90%



Beam deviation <3 arcmin


Features

• optimized for popular laser wavelengths

• dual wavelength polarizing cubes are also available

• all polarizing cubes are ar coated

• Many polarizing cubes are available from stock

Description

optically contacted polarizing beamsplitter cubes are optimized for superior performance in high power applications. these cubes can with stand energy fluencies up to 20 J/cm2 @ 1064 nm for 10 ns pulses at 20 Hz. High energy beamsplitter cubes are easier to mount than thin film polarizers thus making them easier to use in laser setups. High surface flatness reduces wavefront distortion making these cubes a perfect optical component for intra-cavity applications.

glan taylor Polarizers

Description

glan-taylor polarizer is designed to transmit only extraordinary polarization of the beam, while ordinary polarization beam is deflected to the housing. typical application of the polarizer is “cleaning” the polarization of a light source, or attenuation of polarized light source. glan-type polarizers has few advantages over thin film polarizers. Firstly extinction ratio of glan-type polarizer is higher than tFP by 2-4 orders of magnitude, which allows to have better polarization purity. second advantage is broadband spectral operation range, whereas tFP are designed for narrow laser line operation. standard polarizers are mounted into barrel type mounts which are convenient for most applications.

glan thompson Polarizers

Description

a glan thompson prism is a birefringent polarizing element which consists of two calcite prisms cemented together.

Because of the cement it has higher transmission than a glan taylor type polarizer due to the reduced reflection losses at the hypotenuse interface but limited useful uV spectral range. the transmitted beam of extraordinary polarization is used. side faces are black painted to absorb the rejected beam.

Nd:YVo4 crystals

Description

Nd:YVo4 is one of the best host crystals for diode pumped solid state lasers.

Neodymium doped yttrium vanadate (Nd:YVo4) is widely used as diode pumped solid state laser material. It has a high laser induced damage threshold, good mechanical and optical properties. Its large stimulated emission cross-section and high absorption of pump radiation make it a suitable crystal for pocket laser pointer.

Nd:YVo4 can produce Ir, green or blue radiation with minor difference in set-up’s. a broad absorption band centered at 807 nm and favorable mechanical properties make Nd:YVo4 well suited for compact, efficient, high power diode-pumped lasers. Natural birefringence gives rise to a highly polarized output at 1064.3 and 1342 nm.

Yb:KgW and Yb:KYW crystals

Description

Yb3+ doped KY(Wo4)2 (KYW) and Kgd(Wo4)2 (KgW) single crystals are well known laser crystals for diode and laser pumped solid-state laser applications.

Yb:KgW and Yb:KYW crystals are used as a lasing materials to generate ultrashort high power pulses. Yb:KgW can be used as ultrashort pulses amplifiers and these crystals are one of the best materials for high power thin disk lasers.

the broad spectral emission band of Yb:KYW allows the tuning of the laser radiation over 1020-1060 nm range and the generation of femtosecond pulses shorter than 70 fs, enhanced storage capacity, wide absorption spectrum at 980 nm and high absorption of pump radiation in a small crystal region allows an efficient use of diode laser pump.

as compared to Yag or glasses used as hosts for Yb3+, KYW and KgdW have the advantage of a larger absorption cross section than Yag, which decreases minimum pump intensity necessary to achieve transparency in the quasi-two-level system of ytterbium.

Yb:Yag crystals

Description

Ytterbium doped Yttrium aluminum garnet (Yb:Yag) crystal is one of the most promising laser-active materials.

It is more suitable for diode-pumping than the traditional Nd-doped systems. It can be pumped at 0.94 µm laser output. compared with the commonly used Nd:Yag crystal, Yb:Yag crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-state lifetime, three to four times lower thermal loading per unit pump power. Yb:Yag crystal is expected to replace Nd:Yag crystal for high power diode-pumped lasers and other potential applications.

Yb:caF2 crystals

Description

due to Yb:caF2 crystal low quantum defect and a comparably long fluorescence lifetime, ytterbium-doped gain media are preferably utilized for high-power diode-pumped systems and laser amplifiers with high optical-to-optical conversion efficiencies. Just recently, ytterbium-doped alkaline-earth fluorides (Yb:caF2) have attracted considerable interest for use in diode-pumped femtosecond (fs) lasers and amplifiers.

alkaline-earth fluorides which can be easily grown by using the standard czochralski or Bridgman technique. It was recently shown that Yb:caF2 single crystal can be grown up to diameters of about 200 mm, which is superior for high-energy short-pulse lasers with centimeter-sized apertures.

cr4+:Yag crystals

Passive Q-switch crystals

Description

Passive Q-switches or saturable absorbers provide high power laser pulses without electro-optic Q-switches, thereby reducing the package size and eliminating a high voltage power supply. Altechna offers a wide range of solid state saturable absorbers such as co:MaLo, cr4+:Yag, V3+:Yag and others.

cr4+:Yag is an excellent passive Q-switch crystal for Nd and Yb doped lasers (especially for Nd:Yag, Nd:YLF or Yb:Yag), if the wavelength is in the range of 900-1200 nm.

V3+:Yag crystals

Description

V3+:Yag is a relatively new material for saturable absorber passive Q-switching in lasers emitting from 1.06 to 1.44 µm, in particular, for 1.3 µm Nd-lasers.

extremely high ground state absorption (gsa) cross section of 7x10-18 cm2 near 1.3 µm and negligible excited state absorption (esa) permits Q-switching of 1.3 and 1.44 µm Nd-lasers without intracavity focusing both with flash-lamp and diode-laser pumping. Negligible excited-state absorption results in high contrast of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10. Finally, excellent optical, mechanical, and thermal properties of the host crystal give an opportunity to design compact and reliable laser sources with this passive Q-switch crystal.

co:spinel (co2+:Mgal2o4) crystals

Description

co2+:Mgal2o4 (or co:spinel) is a relatively new material for saturable absorber passive Q-switching in lasers emitting from 1.2 to 1.6 µm, in particular, for eye-safe 1.54 µm er:glass laser.

High absorption cross section of 3.5 x 10-19 cm2 permits Q-switching of er:glass laser without intracavity focusing both with flash lamp and diode-laser pumping. Negligible excited-state absorption results in high contrast of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10. Finally, excellent optical, mechanical, and thermal properties of the crystal give an opportunity to design compact and reliable laser sources with this passive Q-switch.

Description

Beta Barium Borate BBo is a non-linear optical crystal that combines a number of unique features.

these features of nonlinear BBo crystal include wide transparency and phase matching ranges, large non-linear coefficient, high damage threshold and excellent optical homogeneity. therefore, BBo provides an attractive solution for various non-linear optical applications like oPo, oPa, oPcPa and other. as a result of large thermal acceptance bandwidth, high damage threshold and small absorption BBo is well suited for frequency conversion of high peak or average power laser radiation. the large spectral transmission range as well as phase matching, especially in uV range, makes BBo perfectly suitable for frequency doubling of dye, argon and copper vapour laser radiation, effective cascade harmonic generation (Frequency doublers, triplers, parametric amplifiers and wave mixers) of wide spread Nd:Yag as well as of ti:sapphire and alexandrite laser radiation. Both angle tuned type 1 (oo-e) and type 2 (eo-e) phase matching can be obtained increasing the number of advantages for different applications.

LBo crystals

Description

Lithium Triborate LBos high damage threshold, wide acceptance angle, good thermal stability and wide transmission range make it ideal for frequency doubling of high power lasers.

It is unique in many aspects, especially its wide transparency range, moderately high non-linear coupling, high damage threshold and good chemical and mechanical properties. Its transmission range is from 0.16 µm to 2.6 µm. LBo allows temperature-controllable non-critical phase-matching operation (NcPM) for 1.0-1.3 µm , type I sHg, and also provides room temperature NcPM for type II sHg at 0.8-1.1 µm. It possesses a relatively large angular acceptance bandwidth, reducing the beam quality requirements for source lasers.

KdP, dKdP crystals

Description

Nonlinear single crystals Pottasium Dideuterium Phosphate KdP and dKdP are widely used as the second, third and fourth harmonic generators for Nd:Yag and Nd:YLF lasers.

these crystals are also widely used for electro-optical applications as Q-switches for Nd:Yag, Nd:YLF, ti:sapphire and alexandrite lasers, as well as for Pockels cells. the most commonly used electro-optical crystal is dKdP with a deuteration ratio more than 98%. these crystals are grown by a water-solution method and can be grown up to very large sizes. therefore, they are available as low-cost and large-size finished non-linear components.

For frequency-doubling (sHg) and -tripling (tHg) of Nd:Yag laser at 1064 nm, both type I and type II phase-matchings can be employed with nonlinear single crystals KdP and dKdP. For frequency - quadrupling (FHg, output at 266 nm) of Nd:Yag laser KdP crystal is normally recommended.

aggase2, aggas2 crystals

Description

AgGaSe2 crystal has band edges at 0.73 and 18 µm. Its useful transmission range within 0.9–16 µm and wide phase matching capability provide excellent potential for oPo applications when pumped by a variety of currently available lasers. tuning within 2.5–16 µm has been obtained when pumping by Ho:YLF laser at 2.05 µm; as well as non-critical phase matching (NcPM) operation within 1.9–5.5 µm when pumping at 1.4–1.55 µm. aggase2 has been demonstrated to be an efficient frequency doubling crystal for infrared co2 lasers radiation.

AgGaS2 crystal is transparent from 0.53 to 12 µm. although its nonlinear optical coefficient is lower among the other Ir crystals, high short wavelength transparency edging at 550 nm is used in oPos pumped by Nd:Yag laser; in numerous difference frequency mixing experiments with diode, ti:sapphire, Nd:Yag and Ir dye lasers covering 2.4–12 µm range; in direct infrared countermeasure systems, and for sHg of co2 laser. thin aggas2 crystal plates are popular for ultrashort pulse generation in mid Ir range by difference frequence generation employing NIr wavelength pulses.

Motorized attenuator assembling steps

Step 1. Place polarizers into mechanical adapter. Polarizers must face each other with surfaces coated with polarizing coating. Polarizing coating is marked with an arrow, so you have to put the polarizers with the arrows on the sides facing each other. then fix polarizers with the plastic bolts (use all 4 plastic bolts to fix one polarizer).

NotIce: do not tighten up the bolts too much since it can bend the polarizer and thus distort the laser beam.

Step 2. Put wave plate into attenuator between two mounting rings as shown. Be sure the wave plate is immobilized tightly.

Step 3. attenuator consists of two mechanical parts. You should assemble both mechanical parts together.

Step 4. use fixing screw for tightening both parts together.

Watt Pilot - Motorized attenuator, Broadband Version

Description

Ideal solution for NIr and MId-Ir wavelengths, where wide operation wavelength range is required. Broadband motorized attenuator version incorporates rotating λ/2 waveplate and glan Laser type polarizer which separates s-polarized and p-polarized beams. s-polarized beam is eliminated in a beam dump, while p-polarized beam’s instenisty is continuously tuned by rotating the waveplate. Watt Pilot is essential in systems, where stable adjustment of laser power is necessary. despite stand alone device look, motorized attenuator is very compact and can be easily integrated in custom optical systems.

Features

• Wide operation range in NIr and Mid-Ir spectrum

Beam expanders

Description

Variable beam expander is galilean type telescope, which allows compact design which is reasonable for industrial environment. employed lenses are air spaced, thus expanders are suitable for high power applications. Altechna offers three different types of beam expanders, each type is targeted to specific application:

• For Nd:Yag lasers

• For femtosecond lasers

• For two wavelengths (e.g. high power beam + guiding beam, or fundamental + harmonic)

standard beam expanders are designed for four most popular lasers: Nd:Yag; ti:sapphire; Yb:KgW and Yb:Yag, but custom wavelengths are available. standard mouinting thread is M27x1, which is compatible with common 4-axis mounts.

Models with 1.5x-5x and 1x-8x magnification distinguish by their “fixed-length” design which simplifies both integration and usage.

Features

• expansion ratios 2x-8x; 1x-8x; 1,5x-4x; 1,5x-5x; 5x-8x

• High laser induced damage threshold

• transmission better than 97%

• “Fixed-length” design option

• custom designs available

Fixed ratio Beam expanders

Description

Altechna’s beam expanders are assembled using one diverging and one converging lenses, so there is no focal point inside the beam expander, thus it can be used for high powers. For low expansion ratios (1.3 - 20 times) the galilean beam expander is preferred due to its simplicity and small size. We offer beam expanders made from two, three, or more spherical lens made from BK7, Fs, uVFs or other glasses which suit high power applications. Beam expander for any wavelength between 266 - 2000 nm is available on request.

Features

• From 2X to 12X magnification options

• compact size

• High power applications

• Max input beam diameter (1/e2) of 3-5 mm for diffraction-limited performance

• Mounting thread sM1

• custom magnification on request

Group delay dispersion measurements (GDD)

gdd in optical components is measured in the range between 500 nm and 1650 nm. chromatis (KMLabs) quickly and accurately characterizes the full dispersive properties of optical components and coatings with resolution up to 5 fs2. gdd is measured for s and p polarization simultaneously in reflection and transmission modes at the angles of incidence from 0° to 70°; mirror pairs are mea sured at angles from 6° to 54°. the white light source in chromatis allows characterization of mirrors designed for ti:sapphire (around 800 nm), Yb:fiber (around 1030 nm), and er:fiber (around 1550 nm).

chromatis (KMLabs)

Goniometer

High accuracy goniometer with air bearing rotary table allows measuring angles for prisms, polygons, wedges and plano optics with accuracy better than 0.6 arcsec. developed software kit allows to determining refraction indices to identify glass types.

Interferometer

For accurate metrology of surface form for flat and spherical surfaces we are using ZYgo Verifire XP/Z Phase shifting interferometer. a wide variety of accessories allows to our engineers to measure coated and uncoated optics, while radius metrology allows us to test spherical surfaces for form irregularities and radius of curvature with radius of ±20 - ±800 mm. For polarization sensitive optics, such as laser crystals, linear polarization option is used.

Verifire XP/Z (Zygo)

Lens testing

Non-contact and less damaging method is used for lens radius of curvature, focal length and centration measurements. air bearing stage and electronic collimator allows reaching less than 0.1 µm accuracy when measuring centering errors. additional accessories extend our capabilities to measure focal length values up to ± 5 meters, roc – ± 750 mm.
